The Interpretation of QR Codes from the Perspective of Pierce's Semiotics

As a new favourite in the digital age, the emergence of QR codes has brought great convenience to human life. The QR codes symbols composed of geometric figures have the ability to carry meaning. Based on Peirce's semiotics, this study explores the relationship between the referents of QR codes, the derivation of signifier process and the communication process. The research finds that: (1) Icon, index and symbol are in a dynamic relationship; (2) The derivation of of signifier process of QR codes depends on the "interpretant"; (3) The communication process of QR codes is mostly culture-based. Through the interpretation of QR codes, this study aims to deepen people's understanding of QR codes and to help them better interpret the meanings implied by QR codes.
